 Find a place in the Software Engineering Guide to discuss RTEMS POSIX
 capabilities are a union of code newlib, RTEMS, and rtems-libbsd. Here are
 some basics to start with.

 * Newlib owns all POSIX and libc/libm headers. Public networking headers
 here even though implementation is elsewhere.
 * Newlib owns implementations of most libc/libm and much POSIX when
 shareable.
 * RTEMS owns RTEMS specific implementations -- threading, system calls,
 signals, malloc, other POSIX
 * Libbsd owns network stack plus some other stuff -- I have trouble
 defining the "some other stuff"
